DATING-STAMP LOCK.

Application filed August 10, 1923. Serial No. 656,650.

To all whom it may concern:

Be it known that I, AUeUs'rUs MILLER, a citizen of the United States, and a resident of East Orange, in the county of Essex and State of New Jersey, have invented a new and Improved Dating-Stamp Look, of which the following is a full, clear, and exact description.

This invention relates to dating stamps and particularly to an improved locking device for looking the legend carrying membore in different adjusted positions and has for an object to provide an improved construction which is simple and effective while at the same time is constructed in such a manner. as to be placed on the clamping structure without interfering with the usual operation thereof. 1

Another object of the invention is to provide a locking device for dating stamps in which a spring retained locking dog or pawl is provided adapted to interlock with the legend carrying belts.

In the accompanying drawing- Figure 1 is an elevation of a standard dating stamp of a reversing variety.

Figure 2 is a sectional view through Figure 1, approximately on line 2-2.

Figure 3 is a perspective view on an enlarged scale, of the locking structure shown in Figures 1 and 2.

Referring to the accompanying drawing by numerals, 1 indicates a dating stamp of any usual or preferred structure, as for instance, a stamp of the same kind as disclosed in my prior Patent No. 1,352,300. This stamp is provided with a suitable frame 2 carrying a handle 3 which is connected with a reversing structure a carrying the various drums 5. These drums are connected with suitable hand operated shifting wheels 6 which are roughened or corrugated to permit a proper actuation thereof so as to shift the Various legend carrying belts 7. It will be noted that the structure 4. is provided with a plate 8 through which the belts 7 project at one point as they pass over the guide 9. All the structure just described is old and well known and forms no part of the presentinvention except in combination.

Heretofore, when the various belts 7 have been adjusted to give the proper date or other information, they would sometimes slip and move out of operative position,

particularly after they had been used for some time. To obviate this slip-ping or shifting of the belts and of the drums 5, the locking structure shown in Figure 3 has been provided. This locking structure consists principally of a body 10 and a looking member or dog 11. The body 10 is preferably formed of sheet metal and provided with a base 12 and a pair of resilient upstanding side members 13 and 14L having a continual tendency to move toward each other in order to pinch the tongue section 15 of the dog ,11. Apertures l6 and 17 are provided in the sides 13 and 1 1, said apertures merging into adjoining apertures in the base 12 by reason of the fact that the retaining tongues 18 and 19 are pressed therefrom, said tongues being passed through suitable apertures in plate 8 and clinched for firmly locking the body 10 in place. It is, of course, evident that the body 10 could be secured in place in some other manner but this has been found to be a very simple and strong connection.

The apertures 16 and 17 act as openings for receiving the respective journal extensions 20 and 21 formed at the lower part of tongue 15 whereby said tongue is pivotally mounted in the body 10. The upper end of the body 10 is provided with inwardly extendingfianges 22 and 23, which flanges are somewhat rounded to provide a notch 24 at each end as well as a shoulder effect 25 at each end. In turn, stops 26 are arranged at each end of the respective flanges 22 and 23 for limiting the back and forth movement of the tongue 15. The tongue 15 merges into a transversely extending plate 27 which is bent over and forms catches 28, 29 and 30, suitable slots 31 and 32 being provided for accommodating two of the wheels 6 and permitting the end edges of the members 28, 29, impinging against the belts 7 between the type. A thumb member 33 is pressed up from the catch 29 whereby the dog may be swung inwardly or outwardly as desired. When the dog is swung inwardly, as indicated in the drawing, the flanges 22 and 23 pinch the same and prevent an accidental outward movement, certain of the shoulders 25 assisting in holding the dog against return movement. However, when the thumb member 33 is grasped and pulled outwardly, the dog will swing outwardly until it strikes the outer stops 26 where it is held by the fact that the sides are resilient and press against the same.

In operation, after the device has been applied to a stamp, the dog is swung outwardly and the various belts 7 adjusted to the desired position and then the dog swung inwardly where it is left until it is again desired to change the position of certain of the belts. As the device is mounted on the plate 8, it will move with said plate and the various drums 5 and belts 7, as these members reverse after each stamping operation.

What I claim is 1. The combination with a dating stamp, of locking means therefor comprising a dog adapted to interlock with the belts of the dating stamp, and a pair of pinching members for locking the dog against accidental movement.

2. A locking means for use in connection with the printing mechanism of a dating stamp where the dating stamp is provided with a base, comprising in combination a body rigidly secured to said base, said body being formed with a pair of resilient pinching side members, and a dog pivotally mounted on said body formed with catches adapted to engage certain of the printing mechanism of the stamp and with a section adapted to be pinched by said side members.

3. A locking means for use on dating stamps which has a printing mechanism mounted on a swingable structure, comprising a substantially U-shaped body formed with pinching and locking flanges, said body being resilient, means for connecting said body with said swingable structure, and a dog pivotally mounted on said body and held in either of two adjusted positions, said dog having catches projecting'therefrom for engaging said printing mechanism.

4. The combination with a dating stamp provided with a plurality of belts having spaced legends thereon and notched shift wheels for shifting said belts, of a lock for said wheels and said belts, said lock comprising a body having spring pressed arms, a dog pivotally mounted on said body provided with a tongue section adapted to be pinched by said spring pressed arms, said dog having a turned over section presenting a catch for each of said belts, and a. notched portion for permitting straddling of each of said wheels. 7
